The act or process of reabsorbing.
Refers to reabsorption by renal tubular epithelium from glomerular filtrate of bicarbonate, sodium and glucose, amino acids, etc.
The process by which solutes, filtered from blood at the glomerulus, are transported back from the tubular fluid into capillary blood.
The return to the blood of most of the water, sodium, amino acids, and sugar that were removed during Þltration; occurs mainly in the proximal tubule of the nephron.
Absorbing again. For example, the kidney selectively reabsorbs substances such as glucose , proteins, and sodium which it had already secreted into the renal tubules. These reabsorbed substances return to the blood. See the entire definition of Reabsorption
In physiology, reabsorption or tubular reabsorption is the flow of glomerular filtrate from the proximal tubule of the nephron into the peritubular capillaries. This happens as a result of sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells. Thus, the glomerular filtrate becomes more concentrated, which is one of the steps in forming urine.
